/*
Devices can either be implemented in C, or in Java.
We therefore have to think about 4 possible call combinations.
1) C -> C:
The standard mupdf case. No special worries here.
2) C -> Java:
This can only happen when we call run on a page/annotation/
displaylist. We need to ensure that the java Device has an
appropriate fz_java_device generated for it, which is done by the
Device constructor. The 'run' calls take care to lock/unlock for us.
3) Java -> C:
The C device will have a java shim (a subclass of NativeDevice).
All calls will go through the device methods in NativeDevice,
which converts the java objects to C ones, and lock/unlock
any underlying objects as required.
4) Java -> Java:
No special worries.
